Referring more in detail to the drawings:

The reference numeral 1 generally designates an-article retrieving apparatus enclosed within a housing 2 having upper and lower compartments 3 and 4 respectively, with a suitable power source, such as a storage battery 5, mounted in the lower compartment 4 and the operative elements of the article retrieving apparatus I mounted in the upper compartment 3.

In the illustrated structure, an article 6 to be retrieved, such as a golf ball, projectile, plumb weight or the like, which is to be cast, propelled, or driven away from the article retrieving apparatus 1 and to be returned thereto, is affixed to one end of a suitable flexible member, such as a line or cord 7 having the other end thereof secured to a storage bobbin 8. The storage bobbin 8 is movably supported on a frame 9, upstanding from a base member 10 which is in the form of a generally horizontal partition or wall separating the upper and lower compartments 3 and 4.

A motor 11 is suitably supported within the upper compartment 3, as by being mounted on the base member 10 or the frame 9. A switch 12 is mounted on a topwall 13 of the housing 2 and is operatively connected to the power source 5 and the motor 11 by conductors 14 and 15 respectively and a conductor 16 extends between and is connected to the battery '5 and the motor 11 to complete a circuit for activating the motor 11 whenthe switch 12 is moved to an on position, as by being depressed.

A pinion gear 17 is rotated by the motor 11 and interengages with a gear 18 mounted on a rotatable shaft 19, spaced above the base member 10 and rotatably supported on the standard 9, as by a suitable bearing or bushing mounted in arms 20 extending from the standard 9 for supporting the rotatable shaft 19 intermediate its ends. 7

The gear 18 is positioned on one side of arms 20 extending from the standard 9 to balance that portion of the shaft 19 positioned on the opposite side of the arms 20. The rotatable shaft 19 has a bore 22 extending longitudinally therethrough and coaxially therewith and a portion of the bore 22 has a flat surface 23 for engagement with a flat surface 24 of a spinner support shaft 25 which is received within the rotatable shaft 19, as later described. I

An exterior surface of the rotatable shaft 19 has a guide groove 26 therein arranged in a pattern to effect reciprocation of the storage bobbin 8 within a cap 27 mounted on the spinner support shaft 25 adjacent one end thereof for rotation with the spinner support shaft 25. The cap 27 has an annular flange 28 enclosing a portion of the storage bobbin 8'during reciprocation thereof. A free edge of the flange 28 guides the line or cord 7 onto the bobbin 8, as later described.

A spool bushing 29 is sleeved on the rotatable shaft 19 and has an aperture 30 therein for receiving a pawl 31 which is engageable within the guide groove 26 for travel therein to effect reciprocation of the spool bushing 29 when there is relative rotation between the bushing 29 and the rotatable shaft 19. The storage bobbin 8 has a keyway 3 2 to receive a key such as an enlarged portion of the pawl 31 for securing the storage bobbin 8 on the spool bushing 29.

The spool bushing 29 has a groove 34 in an exterior surface thereof and adjacent one end to receive a retainer ring 35 for engaging one end of the storage bobbin 8. The spool bushing 29 has an enlarged portion 36 at the other end thereof, forming a shoulder 37, to

be engaged by the other end of the storage bobbin 8 whereby the bobbin 8 is positioned between theshoulder 37 and the retainer ring 35. t

In the illustrated structure, the storage bobbin 8 has a body portion 38 with a pair of .spaced substantially parallel annular flanges 39 and 40 extending therefrom. It is desirable to hold the bobbin 8 against rotation during thereciprocation thereof; therefore, a guide arm 41 is mounted on and extends outwardly from one of the annular flanges, for example flange 40, and the arm 41 is received in an aperture 43 in a housing 44 supported on the arms of the standard 9. The guide arm 41 has a length sufficient to maintain a portion thereof within the aperture 43 duringthe reciprocation of the bobbin 8 whereby the bobbin 8 is held against rotation during reciprocation. i

The cap 27 has a pin- 45 resiliently mounted thereon and movable between an extended position 46 and a retracted position 47. A free end'of the pin 45 is posi' tioned exteriorly of the cap 27 when the pin 45 is in the.

extended position 46 whereby the flexible member 7 is engaged by the pin 45 and wound around the bobbin 8 in response to rotation of the cap 27.

. A suitable resilient member, such as a leaf spring 48 is mounted on'an interior surface of the cap 27 and is adapted to urge the pin 45 toward the retracted position 47. The pin 45 is mounted on one end of a bar 49, having the other end thereof shaped to ride on the exterior surface of therotatable shaft 19.

The spinner support shaft is resiliently mounted in the bore 22 of the rotatable shaft 19 by a suitable resilient member, such as an elongate helical spring 50 sleeved on the spinner support shaft 25 at one end thereof, and'the spring -50'has opposite ends in engagement with one endof the rotatable shaft 19 and one end of the spinner support shaft 25 respectively, for urging an enlarged portion 51 at the other end of the spinner support shaft 25, into seating engagement within a recess 52in the other end of the rotatable shaft A push rod 53- has one end positioned within the housing 2 and aligned with the spinner support shaft 25 to engage the resiliently mounted end of the spinner support shaft 25. The push rod 53 has the otherend thereof extending ex-teriorly of the housing 2 with an enlarged portion 54 thereon. When the enlarged end 54 and the push rod 53 are moved toward the spinner support shaft 25, the spring 50 will be, compressed permitting the cap 27 to be moved to a position spaced from the adjacent end of the rotatable shaft 19. The leaf spring 48 then urges the bar 49 between the cap 27 and the adjacent end of the rotatable shaft to maintain the spacing therebetween and to maintain the pin 45 in the retracted position 47.

The bar 49 has an enlarged portion 55, having, at one end thereof, a lower surface 56 shaped and positioned to be engaged by one of a plurality of cam surfaces 57 mounted on an exterior surface of the annular flange 39 of the bobbin 8 to move the free end of the pin'45 to the extended position 46 in response to rotation of the rotatable shaft 19 and reciprocation of the bobbin 8.

The cap 27 is spaced inwardly from a side wall 58 of.

the upper compartment 3 of the housing 2. A sleeve 59 is mounted in the side wall 58 and has a'bore therethrough for guiding the flexible member 7 into enmas 4 gagement with the pin 45, when same is in the extended position 46.

in use the housing 2 having the article retrieving apparatus 1 therein is carried to-a desired location by a suitable handle 60 mounted on the top wall 13 of the housing 2. The enlarged end' 54 of the push rod 53 is moved toward the housing 2, thereby moving one end of the push rod 53 into engagement with the end of the spinner support shaft 25 to position the cap 27 in spaced apart relation with the adjacent end of the rotatable shaft 19. The leaf spring 48 then urges the bar 49 between the cap 27 and the rotatable shaft 19 to move the pin 45 to the retracted position 47 within the cap 27. The article 6 is then free to be cast, driven, or projected from the article'receiving apparatus 1, and the line or flexible member 7 is free to unwind from the bobbin in a substantially drag-free manner when the article, such as the golf ball 6, is driven from the article retrieving apparatus 1'. When it is desired to retrieve the golf ball 6, -or similar article, the .switch 12 is depressed as by pressing thereon with the foot or golf club of an operator (not shown) thereby completing a circuit betweenthe power source or battery 5 and the motor 11 to effect rotation of the shaft 19 which rotates the shaft 25 and the cap 27 mounted thereon. Rotation of the shaft 19 effects reciprocation of the bobbin'8 which moves one of the cam surfaces 57 thereon into engagement with the-lower surface 56 of the enlarged portion 55 of the bar 49 to overcome the resistance of the leaf spring 48 and move the bar 49 out of the position between the cap 27 and the end of the shaft 19 and move the pin 45 to, the extended position 46. The spring 50 moves the enlarged portion 51 into seating engagement within the recess 52 in the shaft 19, whereby the bar 49 is supported on theexterior surface of the shaft 19 and the pin 45 is maintained in the extended position46. Continued rotation of the cap 27 winds an intermediate portion of the flexible member 7 around the body portion 38 of the bobbin 8 during reciprocation thereof. The distance between facing surfaces of the flanges 39 and 40 of the bobbin 8 is substantially equal to the length of the travel of the bobbin 8 during reciprocation and the free edge of flange 28 of the cap 27 is positioned to align with one of the facing surfaces of the flanges 39 and 40 at one end of the reciprocation and to align with the other of the facing surfaces at the other end of the reciprocation. The

speed of rotation of the cap 27 is coordinated with the speed of the reciprocation of the bobbin 8 to effect smooth winding of the line 7 in diagonal layers on the.

body member 38. When the article 6 has been moved into engagement with an exterior surface of the side retrieving apparatus 61 mounted within a housing 62 having upper and lower compartments 63 and 64 respectively, separated by a partition or base support 65 having a frame 66 pivotally mounted within the upper compartment 63.

A suitable power source 67, such as a battery, is mounted in the lower compartment 64 and electrically connected to a motor 68 and a switch 69 by conductors 70 and 71 respectively. A conductor 72 extends between the switch 69 and the motor 68 to energize or iospiz 0074 activate the motor 68 when the switch 69 is moved on an on" position.

In the illustrated structure, the motor 68 is mounted on the frame 66 and is movable therewith. A shaft 73 is rotated by the motor 68 through interengagement between gears 74 and 75-mounted on the shaft 73 and driven by the motor 68 respectively. A bobbin 76 is sleeved on the shaft 73 and rotatabletherewith.

lnthe illustrated structure, a knob or handle 77 is positioned outside the housing 62 and'above the top wall 78 of the housing 62 and a rod 79 extends downwardly therefrom-and is fixedlyconnected to the frame 66 adjacent an upper end thereof. A lower end of the standard or frame 66 has a rod 80 pivotally mounted on the partition 65 whereby turning-the handle or knob 77 pivots the standard or frame 66 and the bobbin 76 mounted thereon.

' In the illustrated structure, the bobbin 76 has a body portion 81 and a pair of spaced substantially parallel annular flanges 82 and'83 extending therefrom. The bobbin 76 is positioned adjacent a side or end wall 84 of the housing 62 and a sleeve member 85 is mounted in the side or end wall 84 and has a bore 86 therethrough.

The switch 69 is preferably of the push-pull type and has a push-pull bar 87 connected thereto. The pushpull bar 87 is positioned outside the side or end wall 84 and has a center portion .88 parallel with the wall 84 and aligned with the bore 86 through the sleeve member 85. The push-pull bar 87 is movable between an extended or on position and a retracted or of position. v

In using the modified article retrieving apparatus 61, the housing 62 is placed on a suitable support surface and an article 89 to be retrieved, such as golf ball, is moved outwardly from the housing 62 and placed on a suitable support, such as golf tee 90. The knob or handle 77 is turned to position a central axis 91 of the shaft 73 and bobbin 76 in alignment with the bore 86 through the sleeve member 85. The golf ball 89 is then driven by a suitable club (not shown) and a flexible line 92 having one end affixed to the golf ball 89 is unwound from the bobbin 76 in a substantially drag-free manner. When it is desired to retrieve the article or golf ball 89, the knob or handle 77 is turned to align the space between the flanges 82 and 83 of the bobbin 76 with the bore 86 of the sleeve member 85 to thereby position the central axis 91 of the shaft and bobbin 76 normal or perpendicular to the axis of the bore 86. The switch 69 is then moved to the on position to complete a circuit to the motor 68 which effects rotation of the shaft 73 and the bobbin 76 to wind the flexible line 92 around the body portion 81 of the bobbin 76. When the article 89 engages the center portion 88 of the push-pull bar 87, the bar 87 is moved to the of or retracted position to break the circuit to the motor 68.

It is to be understood that while I have illustrated and described certain forms of my invention, it is not to be limited to these specific forms or arrangement of parts herein described and shown.
